Capacitors may catastrophically fail when subjected to voltages or currents beyond their rating, or as they reach their normal end of life. Dielectric or metal interconnection failures may create arcing that vaporizes the dielectric fluid, resulting in case bulging, rupture, or even an explosion. Capacitors used in RF or sustained high-current applications can overheat, especially in the center of the capacitor rolls. Capacitors used within high-energy capacitor banks can violently explode when a short in one capacitor causes sudden dumping of energy stored in the rest of the bank into the failing unit. High voltage vacuum capacitors can generate soft X-rays even during normal operation. Proper containment, fusing, and preventive maintenance can help to minimize these hazards.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can happen to capacitors used in high energy capacitor banks?
Ah, so.. violently explode

The Canadian Rangers, who provide surveillance and patrol services in Canada's arctic and other remote areas, are an essential reserve force component used for Canada's exercise of sovereignty over its northern territory.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which force are the Rangers part of?
Ah, so.. reserve force

Chopin's mazurkas and waltzes are all in straightforward ternary or episodic form, sometimes with a coda. The mazurkas often show more folk features than many of his other works, sometimes including modal scales and harmonies and the use of drone basses. However, some also show unusual sophistication, for example Op. 63 No. 3, which includes a canon at one beat's distance, a great rarity in music.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of bass do Chopin's mazurkas exhibit?
Ah, so..
drone bass
